ELECTRIC LAMP.

Application filed June 25.

To (171 whom it may concern:

Be it known that I, T'TOMER KIMURA, a citizen of the United States,residing at Gunn. in the county of Sweetwater and State of \Vyoming.have invented new and useful Improvements in Electric Lamps, of whichthe following is a specification.

This invention contemplates the provision of a portable electric lampmounted upon a support for universal adjustment to permit the light raysto be thrown in any desired direction. and to also increase and decreasethe area of illumination with a consequent variance of the intensity ofthe light as the occasion may require, together with means for holdingthe lamp fixed in adjusted position.

The nature and advantages of the invention will be better understoodfrom the following detail description of the device, when considered inconnection with the accompaying drawings wherein like numerals ofreference indicate similar parts in the several views and wherein Figure1 is a front elevation of a lamp constructed in accordance with myinvention. Fig. 2 is a side view. Fig. 3 is a rear elevation. Fig. 4 isa top plan showing the lamps adjusted away from each other. Fig. 5 is asimilar view showing a diiferent adjusted position of the lamps. Fig. 6is a View of the same folded. Fig. 7 is a perspective view of one of thelamps removed. Fig. 8 1s a transverse sectional view therethrough. Fig.9 is a detail view of the post. Fig. 10 is an enlarged detail viewshowing one manner of supporting the lamp.

Referring more particularly to the drawings 5 designates a post having acollar or shoulder 6 adjacent the lower end thereof, a pair of wingsbeing indicated at 7 and 8 respectively. The wing 7 is formed to providespaced knuckles 9, while the adjacent edge of the wing 8 terminates toprovide an intermediate knuckle 10 disposed between and in line with theknuckles 9 for the reception of the post 5 adapted to be passed throughthe knuckles. 'By reason of this construction it will be noted that thewings are mounted upon the post for relati ve adjustment, or in otherwords are adapted to be moved toward and away from each other whendesired, and held in any angular position by means of the button 11adjustably mounted upon the upper end of the post 5 and adapted to bindthe knuckles for Specification of Letters Patent.

the respective wings between the said buttons and the collar (3. Each ofthe wings has secured thereto in any suitable manner the lamp which maybe of any particular type suitable for the purpose, but as shown in thisparticular instance includes a parabolic reflector 12 having arrangedtherein an electric bulb 13. the butt 14 of which is preferably threadedthrough a nipple 15 into a receptacle 16 threaded upon the nipple andincluding a contact plate 17 for engagement with the central contact 18of the electric bulb. The enlarged end of the reflector is closed by thelens 19 which is held associated with the reflector in any suitablemanner.

20 indicates a handle for the lamp adapted to be associated with thepost 5 to permit the lamp to be conveniently handled as Well as topermit the same to be carried from place to place. The handle may beassociated with the post in any suitable man-- ner preferably'by meansof a lug 21 arranged at one end of the handle, and a yoke 22 arrangedupon the lower end of the post 5 and which may form an integral partthereof. The lug 21 is adapted to be passed between the parallelportions of the yoke, and provided with a central opening adapted toregister with alined openings in the said parallel members of the yoke,and through which ispassed a bolt 23 and held associated therewith bymeans of a thumb nut 24. lvlanifestly this construction provides for anadjustment between the handle and the lamps, to permit the lamps as aunit to be moved forwardly or rearwardly to different angular positionswith respect to the handle and held in this position by means of thethumb nut 24. This adjustment together with the relative adjustmentbetween the lamps provides what may be termed a universal adjustment topermit the lamps to be adjusted independently or simultaneously toalmost any position as the occasion may require.

The device in its entirety may be used as an automobile trouble lamp,although it is susceptible to an unlimited number of uses, and for thepurpose of suspending the lamp when desired, from a suitable support Iemploy a hook-like element 25 terminating to provide an eye 26 embracingthe shank of a headed bolt 27 which latter is passed transverselythrough a suitable opening in the handle and held associated therewithby means of a thumb nut 28. The bolt is provided with a squared portion29, which n...

tion is embraced by the eye 26 to prevent casual rotation of the hookelement, subsequent to being moved to adjusted position. It will bemanifest by reason of this construction that the hook element may beswung to any angular position with relation to thehandle, to permit thelamp to be suspended or mounted upon almost any form of support, and ifnecessary the lamp subsequently adiusted to the proper position with aview of throwing the light upon the work. The adjustment of the hookelementis obtained by merely loosening the thumb nut 28 and rotating thebolt 27 together with the hook until the latter is forced to assume theproper position, and of course held in this position by tightening thethumb nut 28. Should it be desired to support the lamp vertically upon atable, working bench or other horizontal support, the hook element 26 isremoved from the handle, and the latter arranged between the parallelmembers 30 of a substantially U- haped bracket 31 secured in anysuitable manner upon the base 32, so that the transverse opening in thehandle will be disposed in a line with the openings in the parallelmembers 30, and through which openings the bolts 27 is adapted to bepassed and upon the free end of which the thumb nut 28 is mounted forthe purpose of holding the parts operatively associated in the mannershown in Fig. 10.

A pair of conducting wires 33 have one end connected with a battery (notshown) or other suitable source of energy, and their opposite endconnected with the binding post 34: mounted upon the wings 8 and 9respectively. One of the wires is ground upon the wing 7, while theother wire is insulated and terminates to provide the branches 35leading to the lamps and connected with the receptacles 16 of therespective lamps in any suitable manner. One of the branches is threadedthrough suitable eyes 36 to hold the branch in proper position so thatthe same will not interfere with the adjustment of the lamps toward andaway from each other. A suitable form of switch 37 is connected with oneof the wires, and mounted upon the handle 20 for opening and closing thecircuit of the lamps.

It will be obvious from the foregoing description, that the lamps may beadjusted in any direction the occasion may require, the lamps whenadjusted in the manner shown in Fig. 4 increasing the area ofillumination, and when moved toward each other as shown in Fig. 5 thearea of illumination is not only decreased, but the intensity of thelight is proportionally varied with re gard to the degree of adjustmentof the lamps toward and away from each other.

' It will be further noted that the lamps may be folded in the mannershown in Fig. 6 so as to reduce the size of the article fortransportation, as well as to protect the lens 19 from being broken. Forthe purpose of transportation the lamps together With the post 5 may beremoved from the handle 20 by reason of the connection between theseparts to permit the various parts to be conveniently packed as will bereadily understood.

It is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent without requiring amore extended explanation. However, I desire to have it understood thatI do not limit myself to the precise construction and arrangement ofparts herein illustrated and described, as various changes in thisrespect may be resorted to when desired as fallv within the scope of theappended claims.
